Designer Olivier Gagnère’s Paris apartment is located in the same neighborhood in which he grew up. But it maintains a well-traveled feel thanks to a blend of his own designs with exotic textiles—like his low-profile sofa covered in an antique suzani from Afghanistan.

In the drawing room of Mehall Griffey and Jerry Maggi’s home in Catania, Italy, the stucco ceiling and painted concrete-tile flooring are both original to the building. The sofa is by Baxter, the antique tabernacle is Austrian, and the 18th-century Flemish painting was found at a Paris flea market. The walls are painted in Farrow & Ball’s Down Pipe.

In the Brussels home of Anne-Marie Midy and Jorge Almada, the velvet sofa, armchairs, bench, and mirror are from the couple’s company, Casamidy. The mantel is original to the early 1900s-era townhouse.

Celia Tejada, Williams-Sonoma’s senior vice president of development and design, drew inspiration from her family’s lively kitchen in Spain to create the sitting area in her San Francisco home. Color and pattern take center stage with a vintage movie light and a mix of pillows.

Lawyer-turned-financier-turned-designer Antonello Radi layers antiques in his palazzo in Foligno—including a gilded mirror in the living room, portraits from Brittany, and a pair of 19th-century slipper chairs that retain their original velvet upholstery.

In Kit and Tim Kemp’s London townhouse, the British hoteliers employ their signature eclectic style, giving the library a jolt of color with a George Smith armchair upholstered in bright stripes.

In her Manhattan pied-à-terre, designer Alessandra Branca shows her Roman roots by covering Italian painted chairs in a Fortuny fabric, and creating a pair of lamps from 18th-century Italian columns.

For his attic apartment in Brussels, French designer Bruno de Caumont uses Regency chairs and an Empire sofa from the Paris flea market to create an eclectic, but tailored look. The color-blocked cocktail tables are his own designs.
